Answer:
199 a 426 students
Step-by-step explanation:
first to see what amount we are talking about in each case, let's see how many students each percentage represents
22% of students: (22 * 1420 students) /100 = 312.4 students
8% of students: (8*1420 students)/100 = 114.6 students
that is, that the average number of students who work part time is 312.4 students. And that number can vary up to 114.6 students above and up to 114.6 students below
that can be expressed as
22% + 8% = 312.4 + 113.6 = 426 students
and
22% -8% = 312.4-113.6 = 198.8≅ 199 students
Answer:
The area is 1,014 cm^2
Step-by-step explanation:
Here, we want to find the total surface area of a cube with side length of 13 cm
what we shall do here is to apply the formula to get the total surface area
Mathematically, that will be
A = 6L^2
so we have
Area = 6 * 13^2
Area = 1,014 square cm
The third one is the correct answer I think
1.5 boys eat 1.5 hot dogs in 1.5 minutes
1.5 boys = 1.5 hot dogs / 1.5 minutes = 1 hot dog / minute
6 boys = 4*1.5 boys = 4*1 hot dog / minute = 4 hot dogs / minute
6 hot dogs / (4 hot dogs / minute) = 6 hot dog minutes / 4 hot dogs = 3 hot dog minutes / 2 hot dogs = 3/2 minutes = 1.5 minutes
